Abstract

Catalytic hydrogenation of the enone III on platinum oxide gave a mixture of the alcohols VIa and VIb, but on palladium-charcoal afforded the ketone V, which was also obtained from VIb. Treatment of the alcohol VIa or VIb with hydrogen on platinum oxide yielded an epimeric mixture of VIa and VIb.
